IMPROVED MACHINE POR MAKING DRAIN WATER PIPES.

T0 ALL WHOM IT MAY CONCERN:

Be it known that I, CHARIES COLLIER, of Charlestown, in the county of Middlesex, and State of Massachusetts, have invented a Hydraulic Machine for Making Drain, Soil, and Water Pipes or Tiles from clay, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which Figure lis a side elevation of my improved machine.

Figure 2 is a plan. l

Figure 3 is a longitudinal vertical section through the centre of the same on the line :v :r of fig. 2.

My invention consists in a new machine forl manufacturing drain, soil, and water pipes or tiles from clay, which is operated by means of hydraulic pressure, the details and construction of which I will now proceed to describe in such terms that others skilled in the art may understand and use my invention.

In the said drawings, A is the bed of the machine, in bearings a, on which are placed the trunnions b of a cylinder, B, which receives the prepared clay from Which'the pipes are to be made This cylinder may be turned on its trunnions, so as to bring it into afconvenient position to'receive-the clay, as seen in red, iig. 1, by means of the handle C, and it is locked both in 4a. vertical and horizontal position by means` of a sliding-bolt, c, which passes through one of the projections 4 or 5, and is operated by the hand-lever cl. D isa piston or plunger, which is turned to t the interior of the cylinder B, and is screwed on to the end of a rod, e, which projects-from the piston E of a hydraulic ram secured to the bed A. This piston is made hollow, and extends beyond the end of the cylinder F, beingr provided with a ange, 6, iig. 3, against which the water acts to force the piston in the direction of the red arrow. The piston D is revolved by means of the handles j', so as to run it back on the screw-rod e, as seen in igs. 1 and 3, to allow the cylinder B to be raised into an upright position,

as seen in red, g. 1,- when it is to be lled with clay; and' when it is returned into a horizontal position, as

seen in black, the piston D is moved forward on the rod e into contact with the clay, this arrangement enabling me to shorten the hydraulic cylinder,and thus economize water.A The cylinder B having been iilled with ciay and returned to its horizontali position, the operator opens the valve g in the pipe h, which admits water under pressure from the supply pipe z' into the cylinder F behind the piston E, forcing the piston or head D against the clay in the cylinder B, which is thus ejected through the orifice or mould Cr at its rear end, the form of which is such as tomake the pipe or tile of the required shape. The pipe thus formed is delivered on to a table, H, which is supported by a rod, j, on which is cut a screw-thread; and this rod is raised or lowered by turning a wheel, I, so as to adjust the height of the table in accordance with the size of the pipe or tile being made When the clay cylinder B is emptied the valve g is closed, and the valve k in the pipe Zopened, which admits water from the pipe z' into the cylinder F in front ot' the ange 6 of the piston E, to driveit back, as required, the valve-m being first opened to allow the water behind the piston to pass'into the pipe n, by which it is carried oli as required. On the return stroke, the water in front of the flange 6 is exhausted through the pipe 7, figs. 1 and 2, which is commanded by the valve o. The pipe n leads from the .cylinder F to the lower end of a cylinder, J, within which works a piston (seen dotted in iig. I) to the upper end of the rod P of which is secured a platform, K, which slides on guide rods L, and is employed as an elevator to raise the clay from the floor below to that on which the machine is placed; the force of Vthe water discharged from the cylinder F being suihcient for this purpose. g is a waste pipe, through which the water is discharged from the cylinder J, and the water from the several waste pipes may be conducted over the building or elsewhere, and u sed for a variety of purposes. If desired, a waste pipe may be connected with the pipe n, through which the water from the cylinderF may be allowed to escape, when it is not required to operate the elevator.

The'employment of hydraulic power in machines of this description is exceedingly economical, as they can be operated at much less cost than when steam power is employed, and the services of a skilled engineer are not required.

O'Zaz'm.

What I claim as myinvention, and desire to secure by Letters Patent, is-

A clay cylinder or receiver, B ,in combinationwith a hydraulic cylinder operating a piston or plunger, D, for ejecting the clay from the receiver in the required form for a pipe or tile, substantially as described.

- I also claim connecting the head or plunger D with the piston E of the hydraulic apparatus, by Ameans-ot'v a screw, e, so thatit may be moved toward andfrom the clay cylinder by hand, for the purpose specified.

CHARLES COLLIER.
